The New York Rangers will most likely enter the playoffs without their number one defenseman. That shouldn't change the future decisions based on this team.
A Ryan McDonagh injury might impact the New York Rangers in more ways than just their chance to finally hoist Lord Stanley's Cup this year.
It should be noted that losing their top defenseman three games before the end of the regular season is something out of a Stephen King horror script. The loss of McDonagh -- blocking a shot no less! -- is something that's going to severely damage a defense that is underwhelming even when fully healthy.
